Improving a Vacuum That Couldn’t Vacuum (RPM & Size Tests)

In this project, I wanted to learn what actually creates static pressure in a vacuum. So I designed and tested three different impeller types (straight, curved, and taller blade geometry) and measured how each one performed. It was found that the blade geometry didn't have a large effect. Thus this time around I set out to experiment with the diameter of the blade and the motor speed.

What I learned:
RPM and diameter are more important than blade shape and height.

Equipment:
-Manometer
-Calipers
-PWM controller
-Esp 8266 Microcontroller
-12V DC motor
